Product details
Overview
74LVT02PW,118 from Nexperia is a 3.3 V quad 2-input NOR gate in TSSOP14 package, designed for high-speed logic interfacing with TTL-compatible inputs and 5.5 V overvoltage-tolerant inputs. It delivers ±32 mA/±64 mA output drive, supports partial power-down via IOFF circuitry, and operates across -40 °C to +85 °C for industrial control and data-path logic applications.
For engineers reviewing the 74LVT02PW,118 datasheet, 74LVT02PW,118 pinout, 74LVT02PW,118 application, or 74LVT02PW,118 equivalent, this device is selected for robust bus interface design where 3.3 V logic must coexist with 5 V systems, require low propagation delay (≤4.4 ns), and maintain signal integrity during power sequencing.
Technical Context
The 74LVT02PW,118 implements four independent NOR gates with complementary CMOS output stages, enabling rail-to-rail switching and bidirectional current capability. Its IOFF circuit actively disables outputs when VCC = 0 V, preventing backflow current into powered-down sections of mixed-voltage systems.
Input thresholds are TTL-compatible (VIL ≤ 0.8 V, VIH ≥ 2.0 V) and tolerant up to 5.5 V regardless of VCC state, while output voltage levels meet VOH ≥ 2.0 V at IOH = −20 mA and VOL ≤ 0.5 V at IOL = 32 mA - ensuring reliable inter-stage logic coupling in multi-supply environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.7 V to 3.6 V - enables stable operation across wide 3.3 V system tolerances and brown-out resilience. |
| Propagation Delay | tPLH/tPHL ≤ 4.4 ns at VCC = 3.6 V - supports >200 MHz toggle rates in synchronous logic paths. |
| Output Drive | +64 mA sink / −32 mA source - drives heavy capacitive loads or multiple TTL inputs without external buffers. |
| Input Overvoltage | 5.5 V tolerant - allows direct connection to 5 V buses without level shifters or clamping diodes. |
| IOFF Leakage | ±100 μA at VCC = 0 V - ensures <100 μA backfeed current during hot-swap or partial power-down sequences. |
| Operating Temp | −40 °C to +85 °C - qualified for industrial ambient conditions without derating below 81 °C. |
| ESD Rating | HBM > 2000 V, CDM > 1000 V - meets JEDEC JS-001/JS-002 Class 2/C3 for board-level handling robustness. |
Pinout & Package
TSSOP14 (SOT402-1) package: plastic thin shrink small outline, 14-lead, 4.4 mm body width, 0.65 mm lead pitch, gull-wing terminations, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 | 1Y, 2Y, 3Y, 4Y | Active-low NOR outputs - each sinks up to 64 mA or sources up to 32 mA with defined VOH/VOL. |
| 2, 5, 8, 11 | 1A, 2A, 3A, 4A | First input per gate - 5.5 V tolerant, TTL-compatible, with ±1 μA leakage at VCC/GND. |
| 3, 6, 9, 12 | 1B, 2B, 3B, 4B | Second input per gate - identical electrical behavior to A inputs; enables full 2-input NOR functionality. |
| 7 | GND | Ground reference - all voltage specs referenced here; requires low-impedance PCB return path. |
| 14 | VCC | Primary supply - powers internal logic and output drivers; IOFF activates when VCC = 0 V. |
Key Features
| Feature | Design Value |
|---|---|
| Partial Power-Down Support | IOFF circuit disables outputs at VCC = 0 V, limiting backfeed current to ±100 μA for safe hot-swap in multi-rail systems. |
| 5.5 V Input Tolerance | Inputs withstand 5.5 V regardless of VCC state - eliminates need for external clamps or level translators when interfacing with legacy 5 V logic. |
| High Sink Current | 64 mA output sink capability - directly drives LEDs, relays, or multiple TTL loads without external transistors. |
| Low Propagation Delay | Typical 2.6–2.8 ns tPHL/tPLH at 3.3 V - enables use in high-speed address/data latching and clock-domain boundary logic. |
| Power-Up 3-State | Outputs remain high-impedance until VCC stabilizes - prevents bus contention during power ramp-up sequences. |
Applications
| Industrial PLC I/O Expansion | Legacy Bus Interface Adapter |

Use Scenario: Adding isolated digital input conditioning to a 3.3 V microcontroller-based PLC module that monitors 5 V sensor outputs. IC Role / Device Role / Timing Role: NOR gate configured as active-low input buffer with 5.5 V tolerant inputs, converting 5 V sensor signals to clean 3.3 V logic levels. Use Value: Eliminates discrete level-shifter components while maintaining <4.4 ns response time for fast edge detection on limit switches or encoder pulses. |
Use Scenario: Bridging a modern FPGA development board (3.3 V I/O) to an older ISA-bus peripheral card operating at 5 V. IC Role / Device Role / Timing Role: Logic-level translator and bus driver using dual-NOR configuration to invert and translate control strobes (e.g., IOW,IOR). Use Value: Provides bidirectional 5 V–3.3 V compatibility with no external biasing, leveraging built-in overvoltage tolerance and ±64 mA drive. |
| Memory Address Decoding | Configurable Reset Logic |
|
Use Scenario: Generating chip-select signals for multiple SRAM or Flash devices sharing a common 3.3 V address/data bus. IC Role / Device Role / Timing Role: Quad NOR used as active-low decoder - combining address bits and enable signals to produce precise /CS outputs. Use Value: Achieves sub-5 ns decoding latency and drives >10 pF trace capacitance without timing skew between channels. |
Use Scenario: Implementing a hardware reset combiner that asserts system reset when either watchdog timeout or manual button press occurs. IC Role / Device Role / Timing Role: Dual-NOR gate wired as OR-NOT function to merge asynchronous reset sources into a single /RESET signal.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC02APW | Lower drive (±24 mA), 1.65–3.6 V supply, no IOFF, 5 V tolerant inputs only when VCC ≥ 2.3 V. | Lacks partial power-down protection; unsuitable for hot-swap or mixed-power domains requiring backfeed prevention. | Select when cost sensitivity outweighs IOFF requirement and system uses only 3.3 V rails with light loading. |
| 74ALVC02PW | Higher speed (tPD ≤ 3.1 ns), same 1.65–3.6 V range, no IOFF, 5 V tolerant only if VCC ≥ 2.3 V. | Superior propagation delay but no power-down isolation - risks bus contention during VCC ramp-down. | Choose for maximum speed in fully powered 3.3 V systems where IOFF is not required for safety or sequencing. |
Compared with SN74LVC02APW and 74ALVC02PW, the 74LVT02PW,118 uniquely combines 5.5 V input tolerance independent of VCC, ±64 mA sink capability, and IOFF-enabled partial power-down - making it the only option among the three suitable for robust 3.3 V/5 V mixed-rail industrial interfaces with hot-swap requirements.

FAQ
Can 74LVT02PW,118 be used with a 5 V supply?
No. The absolute maximum VCC is +4.6 V, and recommended operation is strictly 2.7 V to 3.6 V. Applying 5 V to VCC will exceed limiting values and cause permanent damage. However, inputs tolerate up to 5.5 V regardless of VCC level - enabling safe connection to 5 V signal sources while VCC remains at 3.3 V.
Does 74LVT02PW,118 support hot-swap insertion?
Yes. Its IOFF circuitry disables outputs when VCC = 0 V, limiting backfeed current to ±100 μA. This prevents damaging current flow from live 5 V buses into unpowered circuitry, satisfying hot-swap requirements in modular industrial backplanes and field-replaceable units.
What is the maximum capacitive load this device can drive?
Based on dynamic characteristics and output drive strength, the 74LVT02PW,118 reliably drives up to 50 pF load capacitance while maintaining ≤4.4 ns propagation delay (per Table 9 test conditions). For heavier loads (>50 pF), propagation delay increases linearly - verify timing margins in final layout with actual trace and pin capacitance.
Is there a pin-compatible SO14 version of this part?
Yes. The 74LVT02D in SO14 (SOT108-1) package shares identical logic function, pinout, and electrical specifications with the 74LVT02PW,118 in TSSOP14. Both use the same pin numbering and terminal assignments - allowing direct PCB footprint substitution where board space permits larger SO14 dimensions.
